Flower Phenotypes of mads6-1 mads13-3.

(A) One mads13-3 flower at stage Sp8 showing normal floral morphology.

(B) Longitudinal section of one mads13-3 carpel at stage Sp8 showing abnormal ovule.

(C) One mads6-1 mads13-3 flower at stage Sp8 displaying abnormal palea.

(D) to (H) Scanning electron microscopy analysis.

(D) One mads6-1 mads13-3 flower at stage Sp8 displaying ectopic glume-like structures and abnormal lodicules and stamen development.

(E) One mads6-1 mads13-3 flower at stage Sp8 showing higher-order carpel-like structures in the center.

(F) One mads6-1 mads13-3 flower at stage Sp8 showing the transformation from ovule to carpel-like structure.

(G) One mads6-1 mads13-3 flower at stage Sp6 showing delayed inner floral organ development.

(H) One mads6-1 mads13-3 flower at early stage Sp8 showing new organ primordium in whorl 4.

(I) and (J) Longitudinal sections of mads6-1 mads13-3 flowers showing weak (I) and severe (J) phenotypes in the floral center.

(K) and (L) Floral diagrams of mads13-3 (K) and mads6-1 mads13-3 (L).
